Quote: So why do I need a bronze distributor drive gear if running hydraulic rollers?
because the cam core is billet steel and needs the bronze gear and a bronze fuel pump push rod as mentioned.
on my SB the cam core has a cast iron gear pressed and pined on so the stock gear works.
my lunati roller cam runs stock roller lifters,push rods,rockers,retainers,seals with comp 901-16 spring = single with damper and no machine work,stock retainers/seals
done jerked it and stabed it in the 2nd SB engine with no worrys on another set of roller lifters..something you cant do with a flat tappet hydro or solid.why I consider the roller cam upgrade as an investment
i have 3 roller cams now and a couple stock ones for regrinds
lots more to the BB than a SB so the homework is key to longevity
